DEVICE FOR OPERATING SKYLJGHTS.

SPECIFICATION forming part of Letters Patent No. 725,871, dated April21, 1903.

Application filed February 11 1903. Serial No. 142,888. (No model.)

To all whom it may concern.-

Be it known that I, FORREST REICHARD, a citizen of the United States,residing at Eas ton, in the county of Northampton and State ofPennsylvania, have invented a new and useful Device for OperatingSkylights, of which the following is a specification.

Myinvention relates to devices for operating skylights, and has for itsobjects to proro duce a device of this character which will be simple ofconstruction, inexpensive to manufacture, eificient in operation, andone in which the skylight will be automatically locked at any point fromits open to its closed 15 position, the locking means being-actuated bythe means which serves to perform the opening or closing operation.

To these ends the invention comprises, in a skylight-operating device,the combination,

with a pivoted sash, of an arm pivoted thereto and operated thereby, amovable rack operated by the arm, a pivoted pawl adapted toautomatically engage the rack for locking the sash in any desiredposition, and means for 2 5 operating the sash adapted to simultaneouslyrelease the pawl from the rack.

The invention further comprises the details of construction andcombination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a sectional elevation of askylight having my improved operating device applied thereto andillustrating the sash in its opened'position. Fig. 2 is a similar viewillustrating the sash closed.

Referring to the drawings, 1 indicates a skylight frame or casing havinga sash 2 pivoted therein, as at 3, and adapted to swing on its pivotfrom a closed to an open position.

40 In this connection it is to be noted that the pivotal point of thesash is located intermediate of its longitudinal center and one end,thus permitting the sash to close by gravity when released, ashereinafter explained.

5 5 indicates an arm pivoted near one end to the framework of theskylight and provided at its pivoted end with a segmental rack 6,concentric with the pivotal point of the arm. This arm normally lies ina position parallel with the sash when the latter is in its closedposition and is connected with thesash by a link 7, pivoted to the outerend of the arm and to a suitable clip 8, secured by screws or otherwiseto the sash.-

Qindicates a pawl pivoted at one end to the framework adjacent to therack 6, the pawl being provided with a tooth 10, adapted to engage withthe teeth of the rack for locking the same against movement, and thuslockiug the sash in any desired position, as will be readily understood.The pawl is preferably weighted at its free end to cause it to move bygravityintoengagement with the segment; but it will be understood thatit may be actuated by a spring or in other suitable mannor to cause itsautomatic engagement with the segment.

11 indicates a rope or other flexible connection secured at one end toan ear 12 on'the pawl and passed through a sheave 13, secured to theframework, and a second sheave 14, pivotally connected to the sash at apoint between its pivot and inner end.

15 indicates a second rope secured in any suitable manner to the sash ata point between its pivot and outer end, the function of which willpresently be described.

'17 indicates a shoulder on the rack adapted to engage a similarshoulder 18 on the pawl to limit the opening movement of the sash.

The operation of the device is as follows: Supposing the parts to be inthe position illustrated in Fig. 2, with the sash closed and locked inits closed position by means of the pawl engaging the rack, theoperator, in or- 8 der to open the sash, pulls upon the rope 11, whichaction moves thepawl out of engagement with the rack and holds the sameagainst a suitable'stop 16, shown herein as apart of the framework. Thepawl being in .engageo ment with the stop, a continuous pull on the ropecauses the same to travel through the sheave 14 and exert a downwardpull upon the sash, thus swinging the same on its pivot to an openposition, as illustrated in Fig. 1. 5 When the rope is released, thepawl is moved automatically into engagement with the rack 6, thuslocking the parts and securing the. sash in any desired position. Inorder to close the sash, it is simply necessary to oper- Ioo ate therope 11 to move the pawl out of en gagement with the rack and exert aslight pull on the rope 15"sufficient to swing the sash beyond thecenter of gravity, when it will close by gravity, the speed with whichit closes being governed by the rope 11.

From the foregoing description it will be seen that I produce a devicewhich is at once simple, durable, inexpensive, and efficient inoperation, and one in which the sash will be automatically locked in anydesired position, and in attaining these ends I do not limit or confinemyself to the precise details herein shgwn and described, inasmuch asvarious .l-IIlHOI changes may be made therein without I therefor, a rackpivoted to the framework, an arm carried by the rack, a link connectingthe arm to the sash, a pawl pivoted to the framework and adapted toautomatically engage the rack to lock the sash in any desired posi tion,and means adapted to operate the sash and to simultaneously release thepawl from the rack.

3. In a skylight-operating device, the combination with a framework, ofa sash pivoted therein, a rack pivoted to the framework and providedwith an arm, a link connecting the arm to the sash, a pawl pivoted tothe framework and adapted to automatically engage the rack to lock thesash in any desired position, sheaves carried by the framework and sash,and a rope connected to the pawl and operating in the sheaves andadapted to be operated to open the sash and simultaneously release thepawl from the rack.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

FORREST REIOHARD.
